I am going to use Cometic head gaskets on my 440. I have heard you should put sealer on them but the Cometic website says NOT to.

What do all of you do?



I sprayed mine but I used Hylomar blue. Took them apart and sprayed each layer. I had to take one head off and all I did was wipe them down with thinner, re-sprayed them and used them again. Zero leaks.
